Inputs

MC_PhasingAbsolute

This FB serves to set a virtual absolute offset between the applied master axis and the applied slave axis. The special feature here is that the offset only exists virtually and this FB does not cause any motion control.

From the view of the slave axis, the virtual offset is located on the master axis without the master axis noting it.

As soon as an FB for multi-axes movements ( MC_CamIn , MC_GearInPos , ...) is called with the same master slave configuration, the virtual offset is considered automatically.

An offset set via MC_PhasingAbsolute can be deleted by means of the L_MC2P_ResetPhasing function block without having any impact on the movement of the axis which has been uncoupled in the meantime again.

Inputs

Name Data type	Information/possible settings
master AXIS_REF	Transfer of the axis data structure of the master axis Motion axes (AXIS_REF)
Slave AXIS_REF	Transfer of the axis data structure of the slave axis Motion axes (AXIS_REF)
Execute BOOL	FALSE ä TRUE	Set phase displacement.
PhaseShift LREAL	Absolute phase displacement between master and slave axis
Velocity LREAL	Maximum velocity in [unit/s]
Acceleration LREAL	Maximum acceleration in [unit/s ² ]
Deceleration LREAL	Maximum deceleration in [unit/s ² ]
Jerk LREAL	Maximum jerk in [unit/s ³ ]
BufferMode MC_BUFFER_MODE	Mode for processing successive motion commands BufferMode
Note! If a phasing FB is started with BufferMode "mcBuffered" while another phasing FB is currently being executed, the execution of the first phasing FB is aborted and the second phasing FB is started directly. Thus, the behaviour corresponds to the BufferMode "mcAborted" as a call of a second phasing FB with the set BufferMode is not permissible.

Name

Data type

Information/possible settings

master

AXIS_REF

Transfer of the axis data structure of the master axis

Motion axes (AXIS_REF)

Slave

AXIS_REF

Transfer of the axis data structure of the slave axis

Motion axes (AXIS_REF)

Execute

BOOL

FALSE ä TRUE

Set phase displacement.

PhaseShift

LREAL

Absolute phase displacement between master and slave axis

Velocity

LREAL

Maximum velocity in [unit/s]

Acceleration

LREAL

Maximum acceleration in [unit/s ² ]

Deceleration

LREAL

Maximum deceleration in [unit/s ² ]

Jerk

LREAL

Maximum jerk in [unit/s ³ ]

BufferMode

MC_BUFFER_MODE

Mode for processing successive motion commands

BufferMode

Note!

If a phasing FB is started with BufferMode "mcBuffered" while another phasing FB is currently being executed, the execution of the first phasing FB is aborted and the second phasing FB is started directly. Thus, the behaviour corresponds to the BufferMode "mcAborted" as a call of a second phasing FB with the set BufferMode is not permissible.

Outputs

Name Data type	Value/meaning
Done BOOL	TRUE	Phase displacement has been set.
Busy BOOL	TRUE	Processing is running.
Active BOOL	TRUE	The command of the FB is currently executed. The Active output matters if a motion control is carried out by several FBs (BufferMode).
CommandAborted BOOL	TRUE	The command was aborted by another FB. The motion control of the slave has been taken over by another FB.
Error BOOL	TRUE	An error has occurred. For details see ErrorID . The motion control of the slave must be taken over by another FB.
ErrorID L_IE1P_Error	If Error = TRUE: Error number for the error that has occurred.
AbsolutePhaseShift BOOL	Absolute phase displacement Continuous display as long as Busy = TRUE.
